| 1 | NEWS for rsync 3.0.0 (UNRELEASED) |
| 2 | Protocol: 30 (changed) |
| 3 | Changes since 2.6.9: |
| 4 | |
| 5 | BUG FIXES: |
| 6 | |
| 7 | - Fixed the output of -ii when combined with one of the --*-dest options: |
| 8 | it now itemizes all the items, not just the changed ones. |
| 9 | |
| 10 | - Made the output of all file types consistent when using a --*-dest |
| 11 | option. Prior versions used to output too many creation events for |
| 12 | matching items. |
| 13 | |
| 14 | - The code that waits for a child pid now handles being interrupted by a |
| 15 | signal. This fixes a problem with the pre-xfer exec function not being |
| 16 | able to get the exit status from the script. |
| 17 | |
| 18 | - A negated filter rule now sends the negation option when sending the |
| 19 | filter rules. |
| 20 | |
| 21 | - Fixed a problem with the --out-format (aka --log-format) option: it |
| 22 | would output superfluous directory information for a non-daemon rsync. |
| 23 | |
| 24 | - Fixed a problem with -vv (double --verbose) and --stats when "pushing" |
| 25 | files (which includes local copies). Version 2.6.9 would complete the |
| 26 | copy, but exit with an error when the receiver output its memory stats. |
| 27 | |
| 28 | - If --password-file is used on a non-daemon transfer, rsync now complains |
| 29 | and exits. This should help users figure out that they can't use this |
| 30 | option to control a remote shell's password prompt. |
| 31 | |
| 32 | - Make sure that directory permissions of a newly-created destination |
| 33 | directory are handled right when --perms is left off. |
| 34 | |
| 35 | - Improved --hard-link so that more corner cases are handled correctly |
| 36 | when combined with options such as --link-dest and/or --ignore-existing. |
| 37 | |
| 38 | ENHANCEMENTS: |
| 39 | |
| 40 | - A new incremental-recursion algorithm is now used when rsync is talking |
| 41 | to another 3.0.0 version. This starts the transfer going more quickly |
| 42 | (before all the files have been found), and requires much less memory. |
| 43 | See the --recursive option in the manpage for some restrictions. |
| 44 | |
| 45 | - The default --delete algorithm is now --delete-during when talking to a |
| 46 | 3.x rsync. This is a faster scan than using --delete-before (which is |
| 47 | the default when talking to older rsync versions), and is compatible with |
| 48 | the new incremental recursion mode. |
| 49 | |
| 50 | - Added the --delete-delay option, which is a more efficient way to delete |
| 51 | files at the end of the transfer without needing a separate delete pass. |
| 52 | |
| 53 | - Added the --acls (-A) option to preserve Access Control Lists. This is |
| 54 | an improved version of the prior patch that was available. (If you need |
| 55 | to have backward compatibility with old, patched versions, the new |
| 56 | acls.diff patch that will add that.) |
| 57 | |
| 58 | - Added the --xattrs (-X) option to preserver extended attributes. This is |
| 59 | an improved version of the prior patch that was available. (If you need |
| 60 | to have backward compatibility with old, patched versions, the new |
| 61 | xattrs.diff patch that will add that.) |
| 62 | |
| 63 | - Added the --fake-super option that allows a non-super user to preserve |
| 64 | all attributes of a file by using a special extended-attribute idiom. |
| 65 | There is also an analogous "fake super" option for an rsync daemon. |
| 66 | |
| 67 | - Added the --iconv option, which allows rsync to convert filenames from |
| 68 | one character-set to another during the transfer. The default is to make |
| 69 | this feature available as long as your system has iconv_open(). If |
| 70 | compilation fails, specify --disable-iconv to configure and rebuild. If |
| 71 | you want rsync to perform character-set conversions by default, you can |
| 72 | specify --enable-iconv=CONVERT_STRING with the default value for the |
| 73 | --iconv option that you wish to use. For example, --enable-iconv=. is a |
| 74 | good choice. See the rsync man page for an explanation of the --iconv |
| 75 | option's settings. |
| 76 | |
| 77 | - Added the --skip-compress=LIST option to override of the default list of |
| 78 | file suffixes that will not be compressed when using --compress. |
| 79 | |
| 80 | - The --max-delete option now outputs a warning if it skipped any file |
| 81 | deletions, including a count of how many deletions were skipped. (Older |
| 82 | versions just silently stopped deleting things.) |
| 83 | |
| 84 | - You may specify --max-delete=0 to a 3.0.0 client to request that it warn |
| 85 | about any files that it wants to delete without deleting anything. If |
| 86 | you're not sure what version the client is, you can use the less-obvious |
| 87 | --max-delete=-1, as old and new versions will both treat that as the |
| 88 | same request (though older versions don't warn). |
| 89 | |
| 90 | - The --hard-link option now uses less memory on both the sending and |
| 91 | receiving side for all protocol versions. For protocol 30, the use of a |
| 92 | hashtable on the sending side allows us to more efficiently convey to the |
| 93 | receiver what files are linked together. This reduces the amount of data |
| 94 | sent over the socket by a considerable margin (rather than adding more |
| 95 | data), and limits the in-memory storage of the device+inode information |
| 96 | to just the sending side for the new protocol 30, or to the receiving |
| 97 | side when speaking an older protocol (note that older rsync versions kept |
| 98 | the device+inode information on both sides). |
| 99 | |
| 100 | - A lot more --no-OPTION override options are now supported. |
| 101 | |
| 102 | INTERNAL: |
| 103 | |
| 104 | - The file-list sorting algorithm now uses a sort that keeps any same- |
| 105 | named items in the same order as they were specified. This allows |
| 106 | rsync to always ensure that the first of the duplicates is the one |
| 107 | that will be included in the copy. The new sort was also faster |
| 108 | than the glibc version of qsort() and mergesort() in my testing. |
| 109 | |
| 110 | - Rsync now supports the transfer of 64-bit timestamps (time_t values). |
| 111 | |
| 112 | - Fixed a build problem with older (2.x) versions of gcc. |
| 113 | |
| 114 | - Added some isType() functions that make dealing with signed characters |
| 115 | easier without forcing variables via casts. |
| 116 | |
| 117 | - Upgraded the included popt version to 1.10.2 and improved its use of |
| 118 | string-handling functions. |
| 119 | |
| 120 | - Added missing prototypes for compatibility functions from the lib dir. |
| 121 | |
| 122 | - Configure determines if iconv() has a const arg, allowing us to avoid a |
| 123 | compiler warning. |
| 124 | |
| 125 | - Made the sending of some numbers more efficient for protocol 30. |
| 126 | |
| 127 | - Make sure that a daemon process doesn't mind if the client was weird and |
| 128 | omitted the --server option. |
| 129 | |
| 130 | - Improved the use of "const" on pointers. |
| 131 | |
| 132 | - Improved J.W.'s pool_alloc routines to add a way of freeing older |
| 133 | sections of a pool's memory. |
| 134 | |
| 135 | DEVELOPER RELATED: |
| 136 | |
| 137 | - Rsync is now licensed under the GPLv3 or later. |
| 138 | |
| 139 | - Rsync now has a way of handling protocol-version changes during the |
| 140 | development of a new protocol version. This exchange of sub-version |
| 141 | info does not interfere with the {MIN,MAX}_PROTOCOL_VERSION checking |
| 142 | in older versions (which would be the case if every minor change made |
| 143 | to the protocol in CVS incremented the main PROTOCOL_VERSION value). |
